f129b0d44f If subprogram die is not available then construct new one. 
This can happen if debug info is processed lazily.

dff583ac49 Adjust context for the global variables that are not at file scope, e.g. 
void foo() { static int bar = 42; }
Here, foo's DIE is parent of bar's DIE.

d6da133b85 In Thumb1, the register scavenger is not always able to use an emergency 
spill slot. When frame references are via the frame pointer, they will be
negative, but Thumb1 load/store instructions only allow positive immediate
offsets. Instead, Thumb1 will spill to R12.

1a53fd9356 Don't treat malloc calls with non-matching prototype as malloc. 
Fixes second part of PR5130, miscompilation in FreeBSD kernel, where malloc takes 3 params,
and *does* initialize memory.

cc0c3fe456 Remove explicit enum integer values. They don't appear to be needed, and 
they make it less convenient to add new entries.

a3cf123e86 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

they should not base it on llvm-db (which not following almost any "best practices").

18cecec6a0 SSI needs to require DT and DF transitively, since it uses them outside of its runOnFunction. 
Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.

8cebbc5761 MingW build fixes 
- MingW needs -lpsapi (in ${LIBS}) linked after -lLLVMSystem.
  Noticed by Ronald Pijnacker!

- Some parts of the System library must be build with exceptions on windows.
  Based on a patch by Jay Foad!
